Given that Acatenango had a convent, there was daily Mass attended by cofradías leaders and their wives, who kept lighted candles during most of the ceremony. Also daily, the Franciscans tried to have daily religious teaching for 6 year old girls and older starting at 2:00 pm and for boys of the same age starting at sunset; the class lasted for 2 hours and consisted on memorizing the church teaching and prayers and to make some exercises with the catechism and it was run by a priest or by elder natives, called "fiscales".[5] Adults attended Mass every Sunday and holiday and after mass, there were religious teachings in their own language.[5]

Lent was a time of the year when the friars prepared the natives thoroughly, using their own language to accomplish their goals; every Friday of Lent there was a procession following the Rosary steps all the way to the Calvary temple.[6]

When the State of Guatemala was created on 11 October 1825, after independence from Spain, Acatenango was established as town, and then was raised to a municipality of the Chimaltenango District by a decree from 12 September 1839.[8]

On 15 October 1974, tremors woke up people in the settlements surrounding the Volcán de Fuego at 2:00 AM, followed by rumbling and cinders and ashes falling from the sky, which submerged the town into darkness for a few days. President Kjell Eugenio Laugerud García gave order to evacuate people, most of whom were sorry about losing all of their belongings after the eruption; in the meantime, ash was travelling as far away s the Mexican states of Chiapas and Oaxaca, to the point that Mexican authorities were on alert due to the amounts of it that they were getting.[9]

San Pedro Yepocapa was one of the most impacted towns, ending under more than 1m of ash after the four days that the eruption lasted; approximately 1100 people from Morelia hacienda and annexes had to be evacuated to temporary shelters in neighboring Santa Lucía Cotzumalguapa, Escuintla or Patulul, Suchitepéquez.[10]

Democracia Cristiana Guatemalteca —DCG— directors -then the main opposition party in the country after losing the presidency to Laugerud Garcia in fraudulent elections earlier that year, [11] asked to all the mayors to help their colleagues from San Pedro Yepocapa and Acatenango, which were practically destroyed by the catastrophe; those two mayor belonged to DCG. Help began to arrive on 24 October 1974, when the eruption ceased and equipment from the Road General Direction of Guatemala arrived to the towns to clean them up, and operation that lasted three months.[9]

This massive volcano complex towers more than 3,500 metres above the Pacific coastal plain to the south and 2,000 metres above the Guatemalan Highlands to the north. The volcano complex comprises remnants of multiple eruptive centers, which periodically have collapsed to form huge debris avalanches. The largest of these avalanches extended more than 50 kilometres from its source and covered more than 300 square kilometres.[12] Contrary to its neighbor, Volcán de Fuego, it has been dormant for the last six hundred years.
